32 days in flowering, still no smell???

Is this normal, 4 weeks into flowering and they only smell like plants???
I got these clones from the canabis club, they said they were silverhaze, and purple kush. temp is at 74degrees when light is on, and 64 them light is off.

Can anyone let me know what im doing wrong or if this is normal???

Never grew that strain. Mine are about to finish the 4th week and stink up the whole house. From the basement,can smell them (3) all the way in the bedroom on the second floor on a warm day

That's odd, I'm just growing bagseed and not even into flowering and my whole house smells like a concert. Might want to try that silver haze once if that's common for that strain.
